摘要：
In this paper, the ultrafine powders of the perovskite-type solid solution LaFe1-yCoyO3 (0 less than or equal to y less than or equal to 0.40) were prepared by chemical coprecipitation. The preparation conditions, phase constituents, conductance and gas-sensing proper-ties were investigated. The results demonstrate that LaFe1-xCoyO3 is a p-type semiconducting material and it has high sensitivity and good selectivity to C2H5OH when y = 0.20. (C) 2001 Elsevier Science B.V.
